Permanently deletes a file owned by the user without moving it to the trash. If the file belongs to a shared drive the user must be an organizer on the parent. If the target is a folder, all descendants owned by the user are also deleted.

Permanently deletes a file version. You can only delete revisions for files with binary content in Google Drive, like images or videos. Revisions for other files, like Google Docs or Sheets, and the last remaining file version can't be deleted.
